Cloning and Sequence Analysis of β-1,3-1,4-Glucanase Gene

Abstract:

Based on the sequence alignment of Bacillus amyloliquefaciens,two pairs of primers were designed and synthesized in this study.Using the total DNA of Bacillus amyloliquefaciens as template,the gene of β-1,3-1,4-glucanase(bgl) was amplified by PCR,which has about 750 bp in length.The gene was cloned into pTG19-T Easy vector,and the recombinant plasmid was identified by PCR,restriction enzyme analysis and sequencing.The homology analysis revealed that the nucleotide sequences of the cloned β-1,3-1,4-glucanase gene similar to the B.amyloliquefacines(M15674),B.subtilis(D00518) and B.licheniformis(AY365256)were 99%,95% and 94%,respectively.
